Congrats on your purchase.
Check out Visual Garage's website, they have pictures of all sorts of cars with color matched shark fin antennas. I have one on my Black Cherry Mica and think it looks great. Their paint matching is spot on. I am sure if you didn't want one painted they could accomodate you.
A company called RPM is developing lowering springs with an increase in the spring rate that can be used with the stock struts/shocks. The first set has been installed on a car and they have said they want lower the front a little more, so can't say when their product will be available. AutoEXE springs are currently available through Corksport and others, they give about an inch of lowering but are pricey at over $400.
There are a couple of engine mounts available, AWR, CPe and another one I don't think can be mentioned here. They differ only in hardness of the material used, I have the CPe and it did a lot for taking out driveline lash and making shifting easier/smoother. There is a slight increase in engine vibration at idle, but nothing annoying. Installation is easy if you are mechanically inclined.
Another good mod that I just got done installing is TWM's short shifter and shift bushings. Drops the lever height about 1" and shortens the throws about 35%. The bushings tighten things up so action is more direct.
